refer to Section 6 of the Chassis Overhaul Manual.
Because of the interchangeability and similarity of
many engines, engine sub-assemblies and engine parts,
regardless of which passenger vehicle they are used in,
typical illustrations and procedures are used except
where specific illustrations or procedures are necessary
to clarify the operation. Although illustrations showing
bench operations are used, most single operations, when
not part of a general overhaul, should be performed (if
practical) with the engine in the vehicle.

GENERAL DESCRIPTION
The function of the starting system, composed of the
starting motor, solenoid and battery, is to crank the
engine. The battery supplies the electrical energy, the
solenoid completes the circuit to the starting motor, and
the motor then does the actual work of cranking the
engine.
The starting motor (fig. Is) consists primarily of the
drive mechanism, frame, armature, brushes, and field
windings. The starting motor is a pad mounted 12-volt
extruded frame type, having four pole shoes and four
fields,
connected with the armature. The aluminum drive
end housing is extended to enclose the entire shift lever
and plunger mechanism, protecting them from dirt,
splash, and icing. The flange mounted solenoid switch
operates the overrunning clutch drive by means of a
linkage to the shaft lever.
The V-8 wiring harness differs from the in-line engine
in that the ignition lead to the coil from the switch is at-
tached at the coil instead of at the starter solenoid (fig.
2s).

MAINTENANCE AND ADJUSTMENTS
No periodic lubrication of the starting motor or sole-
noid is required. Since the starting motor and brushes
cannot be inspected without disassembling the unit, no.
service is required on these units between overhaul
periods.
RESISTANCE CHECKS
Although the starting motor cannot be checked against
specifications on the car, a check can be made for. exces-
sive resistance in the starting circuit. Place a volt-
meter across points in the cranking circuit as outlined
below and observe the reading with the starting switch
closed and the motor cranking (distributor primary lead
grounded to prevent engine firing).

GENERAL DESCRIPTION
A diaphragm spring-type clutch assembly is used with
manual transmissions.
The clutch assembly is enclosed in a 360° bell housing
which must be removed to gain access to the clutch.
V-8 engines (equipped with a 4 speed transmission)
use a bent-finger, centrifugal diaphragm type clutch as-
sembly. All its integral release fingers are bent back to
gain a centrifugal boost and to insure quick re engagement
at high engine speeds.
This type of clutch has the advantages of increasing
pressure plate load as the driven plate wears, and of low
pedal effort with high plate loads without requiring over-
center booster springs on the clutch linkage.
The pressure plate is a high tensile strength iron de-
signed for maximum speed conditions.
The clutch release bearing (fig. 4), used with the bent
finger diaphragm clutch, has an overall length of approxi-
mately
1-1/4".
The longer bearing, used with the straight
diaphragm, will cause inability to obtain free pedal travel,
especially as the clutch wears, resulting in slippage and
rapid wear.
DO
NOT INTERCHANGE!
The clutch is operated by conventional linkage consist-
ing of two groups, upper linkage and lower linkage.
The return spring pre-loads clutch linkage, removing
looseness due to wear. The clutch free pedal travel,
therefore, will increase with linkage wear and decrease
with driven disc wear, and free travel felt at pedal is
throwout bearing lash.
MAINTENANCE AND ADJUSTMENTS
LINKAGE INSPECTION
There are several things which affect good clutch op-
eration. Therefore, it is necessary, before performing
any major clutch operations, to make preliminary in-
spections to determine whether trouble is actually in the
clutch.
Check the clutch linkage to be sure the clutch releases
fully as follows:
1.
With engine running, hold the clutch pedal approxi-
mately 1/2" from floor mat and move shift lever be-
tween first and reverse several times. If this can be
done smoothly, the clutch is fully releasing. If shift
is not smooth, clutch is not fully releasing and ad-
justment is necessary.
2.
Check clutch pedal bushings for sticking or excessive
wear.
3.
Check fork for proper installation on ball stud. Lack
of lubrication on fork can cause fork to be pulled off
the ball.
4.
Check for bent, cracked or damaged cross shaft
levers or support bracket.
5.
Loose or damaged engine mounts may aUiow the en-
gine to shift its position causing a bind on clutch
linkage at the cross shaft. Check to be sure there is

some clearance between cross shaft and both its
mounting brackets.
CLUTCH LINKAGE ADJUSTMENT
There is one linkage adjustment (clutch fork push rod
or pedal push rod) to compensate for all normal clutch
wear.
The clutch pedal should have
1-1/4"
free travel (meas-
ured at clutch pedal pad) before the throwout bearing en-
gages the clutch diaphragm spring levers. Lash is re-
quired to prevent clutch slippage which would occur if the
bearing was held against the fingers and to prevent the
bearing from running continually until failure.
Chevrolet Linkage Adjustment (Fig. 1}
With Nuts (A) & (B) loose on Rod (D)
&
before installa-
tion of Clutch Pedal Return Spring
(E),
apply approximately
5 lbs. load in direction of arrow (F) to eliminate clear-
ance between throwout bearing and clutch fingers. Move
Rod (D) in direction of arrow (G) until Clutch Pedal Arm
makes contact with Bumper Stop on instrument panel
brace. Run Nut (B) toward Swivel until dimension (X) is
9/32". Tighten Nut (A) to lock Swivel (C) against Nut (B).
